How to use this

Details

Key

⬋ Grouped async operations. Size represents time spent executing code and waiting for responses.

The straight line segment represents async operations in this group initiated in the previous group.

Colors indicate type and area of the grouped operations (labels above expand to give more details).

How to start exploring this

The diagram shows how groups of async operations branch out from the start point of this application, which is at the top centre.

Click on bubbles to explore deeper. When you reach groupings of only one async operation, call stacks are shown, allowing you to find the code behind the biggest delays.
